5 Pesos 2008 Carlos María de Bustamante: Value & Prices

If you found a Mexican 5 pesos coin dated 2008 with "Carlos María de Bustamante" on it, here is the honest answer: the plain circulated version is worth close to face value, a couple of US dollars at most. The proof version in its original Banxico case is the one collectors actually pay for. Here is how to tell which one you have and what it sells for in 2026.

What this coin actually is

This is a bimetallic 5 pesos coin struck by Banco de México (Banxico) in 2008 as part of the "Bicentenario de la Independencia" program, the series marking 200 years of Mexican independence. Each coin in the set honors a figure from that period. This one features Carlos María de Bustamante, a historian and insurgent politician.

The coin has two parts: an outer ring of aluminum bronze and a center that, in the collector version, is made of .925 sterling silver. That silver center is the reason two versions of the same coin sell for very different amounts.

Specifications

• Weight: 9.76 g
• Diameter: 30.52 mm
• Edge: Plain
• Composition: Aluminum bronze ring, center of .925 silver (proof version)
• Finish: Proof (encapsulated) and regular circulation
• Year: 2008

What it is worth

The value depends almost entirely on which version you have and its condition. This is not a rare coin, so do not expect a fortune. Do not believe listings claiming it is worth hundreds just because it is a "Bicentenario" piece.

Version	Condition	Approximate value (USD)
Regular circulation	Worn / used	Face value, roughly 25 to 50 cents
Regular circulation	Uncirculated	1 to 3 dollars
Proof (silver center, in Banxico case)	Complete with capsule	15 to 40 dollars

The silver center in the proof version gives it a floor value tied to the silver market, but the amount of silver is small, so bullion value alone is only a few dollars. What buyers pay extra for is the proof finish, the mirror-like fields, and the original Banxico presentation case. A proof coin removed from its case and scratched loses most of that premium.

How to tell which version you have

1. Look at the center. A proof coin has a bright, mirror-like surface with frosted design elements. A circulation coin looks flat and matte.
2. Check for a capsule and case. Proof coins were sold sealed in a plastic capsule inside a Banxico box. If yours is loose in a drawer, it is almost certainly the circulation version.
3. Weigh and measure it. Use a jewelry scale and a caliper and compare against the specs above, 9.76 g and 30.52 mm. Correct weight and diameter are the first check for authenticity.

The myth: "errors worth thousands"

Social media is full of claims that this coin has minting errors worth thousands of dollars. Genuine mint errors (off-center strikes, die rotation, double strikes) do exist and can raise value, but they are rare and must be verified. Most of the "errors" people post are post-mint damage: dings, corrosion, or scratches from circulation. That is not an error and it lowers value, it does not raise it. If you think you have a real one, get it looked at before you get excited.

How to check authenticity

Counterfeits of low-value modern coins are uncommon, but if you want to be sure:

• Verify weight (9.76 g) and diameter (30.52 mm) precisely.
• Look for flat, mushy detail or colors bleeding between the ring and center, both signs of a fake.
• For the proof version, confirm the capsule and case look factory-sealed, not homemade.

Where to sell it

Since this is a modern, common coin, keep your expectations realistic and avoid paying anyone to "authenticate" a coin worth a few dollars.

• Numismatic shops: A verified coin shop in the Pesoteca directory can value it on the spot, no middleman markup.
• Collector forum: The Pesoteca buy/sell forum connects you directly with collectors, which matters most for the proof version.
• Complete sets: If you have several coins from the Bicentenario series, they often sell better as a full set than piece by piece.

Photograph the front, back, and edge in good light before listing, and note whether you have the original case. That single detail is what separates a 2 dollar coin from a 30 dollar one.

Have the proof version with the Banxico case, or think you spotted a real minting error? Post clear photos in the Pesoteca forum and let collectors weigh in before you sell.

Carlos María de Bustamante Merecilla: lawyer, insurgent journalist and deputy of the Congress of Chilpancingo

Carlos María de Bustamante Merecilla (1774-1848) was a lawyer, insurgent journalist and deputy of the Congress of Chilpancingo during the War of Independence.

Bustamante founded in 1812 the newspaper El Juguetillo, one of the first outlets of insurgent propaganda. He took part in the Congress of Chilpancingo convened by Morelos and signed the Declaration of Independence of Northern America on November 6, 1813. As a historian he wrote the Cuadro Histórico de la Revolución Mexicana, a reference chronicle of the war.

Context of the year. The piece is from 2008 and gives visibility to the civilian side of the insurgency. In 1813 the movement was in its institutional phase, with the Congress defining political doctrine amid the military campaign.

The reverse of the coin. The reverse of this 5-peso piece shows the portrait of Carlos María de Bustamante Merecilla, his engraved signature and the year 2008, in accordance with the official catalog of the Bank of Mexico for the commemorative series of the Bicentennial of the start of Independence (1810-2010).

Legacy. Several streets and libraries in Oaxaca, his home state, bear his name. His historical work remains a primary source for the study of the War of Independence.
